This invention relates generally to door a pin 18 which extends transversely through latches particularly designed for use upon the extension 4: at the rear end thereof. As the doors of vehicle bodies and consists of shown, this plate is slidably mounted on certain novel features of construction, comthe case plate 1 and is provided with lateral 5 binations and arrangements of parts as will tongues 14 that are adapted to travel in suitbe more fully described and particularly able elongated guide slots 15 in the ease plate pointed out in the appended claims. 1. Any suitable means such as the helical In the accompanying drawings: spring 16 anchored on the case plate 1 may Figure 1 is a fragmentary elevation of be employed for normally holding the plate a door with a latch mechanism embodying 10 in its forward position so that the flange my invention applied thereto. 11 will be in operative position with respect Figure 2 is a fragmentary elevation of the to the rollback 7. latch mechanism. In order that the bolt 3 may be readily re- Figure 3 is a fragmentary elevation of the tracted at a remote point, I preferably proremote operating means. vide a bar 17 that is slotted to receive the arm Figure 4 is a view similar to Figure 3 but 18 of the rollback 8 and that is connected to showing the rollback in dogging position. the slidable plate 10 by means of a rod or Referring now to the drawings, the nulink 19. As shown, the slot 20 in the bar 17 meral 1 designates a latch case plate that is is elongated to permit the bar to be moved 26 secured to the inner side of a door and is rearwardly by the rollback7 without disturbprovided at its forward edge with a laterally ing the rollback 8 and to permit the latter to extending flange 2 that is secured to the outer be swung forwardly as will be hereinafter edge of the door. Slidably mounted on the described. Thus, when the rollback 7 is case plate 1 and movable through a suitable swung rearwardly against the lateral flange 25 opening in the flange2is a latch bolt3having 11, the lugs 12 of the plate 10 will engage a rearwardly projecting cylindrical extenthe pin 13 in the extension 4 and will cause the sion 4 slidably engaging a suitable guide lug bolt 3 to be retracted; likewise when the roll- 5 on the case plate 1. Any suitable means back 8 is swung rearwardly against the rear such as the coil spring 6 sleeved on the exwall 21 of the slot 20, the bar 17 link 19 and 30 tension 4 between the lug 5 and bolt 3 may be plate 10 will move as a unit and will cause the employed for normally holding the bolt in lugs 12 of the latter to engage the pin 13 to projected position. retract the bolt without disturbing the roll- For retracting the bolt 3 against the tenback 7. Hence the rollbaeks 7 and 8 respecsion of the spring 6, I preferably provide two tively may be independently operated. distantly spaced rollbacks7 and 8 respective- Moreover the connection between the bolt 3 ly. As shown, the rollback 7 is journaled in and plate 10 is such that the bolt is free to the case plate 1 adjacent to the flange 2 and move inwardly when the door is closed withis adapted to be operated from theoutside of out disturbing either rollback. the door at a point adj acent to the outer edge In devices of this kind it is desirable to m thereof, while the rollback 8 is swingingly provide some means for rendering inoperamounted on a separate case plate 9 on the in tive the bolt retracting member that is actuner side of the door and is adapted to be operated from the outside of the door. In the ated from the inside of the door preferably present instance this is accomplished by pro at a point substantially midway between the viding the rollback 8 with an arcuate edge may be easily and quickly retracted by the gagement with a correspondingly shaped rerollback 7, I preferably provide a plate 10 cess 23 in the upper edge of the bar 17. Inthat has a lateral flange 11 adapted to be enasmuch as the bar 17, link 19 and plate 10 gaged by the rollback 7 and that has spaced move as a unit, it will be apparent that the laterally projecting lugs 12 engageable' with engagement of the arcuate edge portion 22 with the recess 23 will automatically cause the flange 11 on the plate to hold the roll- I back 7 against rearward bolt retracting movement. Hence, the rollback 7 may be rendered inoperative from a remote" point.

Moreover, the rollback 8 may be moved in one direction to retract "the bolt and may be moved in opposite direction to render the' rollback 7 inoperative, thus, serves a double function. In order that the rollback 8 may be detachably held in position to retract the bolt or in position to render the rollback/Z inoperative, I preferably provide a leaf spring 24 that is secured-at its opposite ends to a marginal flange 25 of the case plate 9 and that is provided intermediate its ends with a substantially ll-shaped finger portion 26 that is adapted to automatically engage the spaced notches or recesses 27 and respectively in the upper edge of therollback ,8.

Thus, from the foregoing description, it

will be readily apparent that the present construction eliminatesthe necessity of passing the latch lever through the garnish rail or molding of the door. Inasmuch as the operating handle (not shown) for the inside rollback 8- is positioned upon the inner side of the door, it. will alsobe apparent'thatit is very accessible and may be easilyand quickly operate for actuating'the bolt. Due to its location, the inside operating handle may also be readily used from the inside of the vehicle to pull the door from opento closed a position.

While it is believed that from the foregoing'description, the nature and advantage of my invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and de scribed and that such. changes'may be re sorted to when'desired as fall within the scope of what is claimed.
